πŸ‘‹ Hello, I'm Valentin !

I'm a Data analyst with strong experience in Python, data modeling and analytical workflows.
I build data-driven solutions to explore, model and interpret complex datasets across various domains.

I hold a PhD in Science, during which I developed numerous methodologies for data analysis, 3D and temporal interpolation, uncertainty estimation, and geostatistical approaches. I published several scientific papers and presented my work at international conferences.

Since then, I have worked in a private engineering company, where I continue to develop data-driven solutions and client-oriented approaches, while strengthening my project management skills.

πŸ”§ Core skills

  • Programming & Data: Python (Pandas, NumPy, SciPy), SQL
  • Data analysis: exploratory analysis, time series, statistical modeling, ML
  • Data processing: data cleaning, pipelines, reproducible workflows
  • Visualization: Dashboard creation, Streamlit, Matplotlib, Seaborn, Plotly, Tableau
  • Tools: Git, Jupyter, Linux

🎯 Interests

  • Data analytics & decision support
  • Applied data science
  • Quantitative analysis in various sectors (finance, energy, consulting, tech)
